Minimally Invasive Surgery (MIS) Bunionectomy

  • Goals

    Correct Alignment: Realign the deviated metatarsal bone and restore proper joint alignment.

    Relieve Pain and Discomfort: Alleviate pain, discomfort, and pressure on the affected joint.

    Restore Functionality: Improve the function of the big toe for weight-bearing activities and walking.

    Prevent Recurrence: Minimize the chances of bunion reformation by addressing underlying anatomical issues.

  • Risks and Complications

    Infection: Any surgical procedure carries a risk of infection, although it is minimized in MIS due to smaller incisions.

    Nerve or Blood Vessel Injury: Rare instances of nerve or blood vessel damage can occur during the procedure.

    Delayed Healing: Some patients may experience delayed wound healing.

    Recurrence: Although less common with MIS, there is a slight risk of bunion recurrence.

    Stiffness: Stiffness or reduced range of motion in the big toe joint may occur post-operatively.

  • Aftercare

    Weight-Bearing: Gradual return to weight-bearing activities as guided by the surgeon.

    Elevate and Ice: Elevate the foot and apply ice to reduce swelling.

    Medications: Take prescribed pain medications and antibiotics as directed.

    Follow-Up Appointments: Attend scheduled follow-up visits for wound checks and assessment of progress.

    Physical Therapy: Engage in physical therapy exercises to regain strength and mobility.

MIS Procedure

Anesthesia: The patient is administered either local or general anesthesia based on their medical condition and preferences.

Incisions: Small incisions, typically less than 5mm, are made near the affected joint.

Soft Tissue Dissection: Specialized instruments are used to gently separate soft tissues, avoiding unnecessary trauma.

Osteotomy: The deviated portion of the metatarsal bone is carefully removed or realigned.

Fixation: In some cases, screws, pins, or plates may be used to stabilize the corrected position.

Soft Tissue Repair: Soft tissues are meticulously repositioned to support the corrected joint.

Closure: The incisions are closed with sutures or surgical adhesive.
